ABS ESP ETS light reset? - PeachParts Mercedes-Benz Forum

mbpros · #1 09-10-2007, 02:45 AM

Hey Pros,
I've been trying to fix the ABS ESP and ETS light on issue on my ML32o (years 2000) by following the solutions from this Support Forum. I have done the following: wheel speed sensor check and cleaning, battery voltage check, brake fluid repalcement, ABS control module diagnostic, ABS and ESP ETX relay replacement and brack switch replacement. So far none of these could make the ABS ESP and ETS light to turn off. I wonder if these warning lights need to be reset somehow if one of the above issue could have resolved the issue. If so, how to reset the warning.

Thanks in advance for your advice,
BR/PY

Hey Pros,

The ABS ESP ETS lights have been turned on my ML320 (Yr2000) for two month. After trying to resolve this issue by following all the possible leads from this Support Forum, I still have not gotten any luck. I have replaced the brake switch, brake fluid, clean up the wheel speed sensor, checked all relays and batteries and have the ABS coil module. After I've exhaused all the quick solutions that helped others to solve this issue. Then I turned to the MB certified shop for their suggestion. Their diagnostic was indicating the the ABS pump module has gone bad (they think by code given) and wanted ~ $4000 dollars to get it fixed. I am not sure how will this possible. I have not heard or seen any case like this on this Forum. I'd like to seek for suggestions from this forum before I take it to the shop. Any suggestion that could save me some $ to fix this will also be very much appreciated.

Thanks in advance,
BR/PY

With computer systems you need a computer scan to determine the problem.

Go to the top of the ML forum and click on search, type in ABS pump and look for my solution to this problem. You can use the same troubleshooting procedure that I did, even if the problem lies elsewhere. The dealers are very quick to replace the ABS pump assy and they blame the leaking window washer tank for shorting this out! NOT likely! The lights will clear themselves if you have eliminated the problem.
